Researchers have developed CoReLIN, a novel framework for lifelong interactive robot navigation that utilizes constraint-based reasoning and large language models. This system is designed to enable robots to navigate complex environments by actively moving objects to clear paths, a capability crucial for sequential object-placement tasks. CoReLIN reasons over a structured scene graph to determine which objects to relocate and where to place them, optimizing for both immediate task completion and long-term environmental navigability. Evaluations in simulation and on real-world hardware demonstrated CoReLIN's superior performance compared to existing methods, introducing new metrics like the Long-term Efficiency Score (LES) and Price of Clutter.
